MOVING Locomotiva-ENGINES BYHAND-Povvnn; f 1

Specification of Letters Patent No. 26,318, dated November 29, 1859;` 1

T o allwhom 'it may concern:

Be it known that I, JOHN E. VVOOTTEN, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Instrument `for Moving Locomotive-Engines and Railroad- Cars for Short Distances upon the, Track; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, in Whichi y Figure l is a perspective view of the instrument, `Fig. 2, a vertical transverse section, Fig. 3, a vertical longitudinal section, and Fig. el, a top view with the capL removed, similar letters referring to similar parts.

It may be proper here to remark that the process of moving a` locomotiveengine or railroad car upon the track by hand is tech- `nically termed pinching and has heretofore been accomplished, chiefly bymeans of an ordinary crow bar.

The `nature of my invention consists in providing a cylinder A, communicating by means of an opening B, with the pump barrel C, the cylinder A should be bored with accuracy and the piston D, nicely fitted to Work Within the same. The pump barrel C, `should also be bored with accuracy and the plunger E, Well fitted to Work Within it. The plunger E is actuated by means of arm F attached to shaft G, which is moved by the hand lever H. The mouth of the pump barrel C is slightly enlarged for the purpose of facilitating the entrance of the plunger E, when it may have been Withdrawn for the purpose of replenishing the supply of fluid to the pump barrel C; this provision renders the use of valves unnecessary as Will be hereinafter shown.

I, is a. reservoir for containing a supply of oil, Water, or other fluid which may be most convenient or desirable for the operation of the instrument.

I Will proceedto explain its `modeof oper-w` ation which is as follows,

The cap L havingl been removed,`V o1l,

1551 Water, or other convenientor, desirableiiuid` i should be poured into the lreservoir I, and in order that the pump barrel C maybe] iilled at the same time,"the

be Withdrawn to the end o "its stroke, when? the entire cavity has been illedthe ca-pL lunger E shouldf y Should be 1@Placed and screvvedi` downitowa l joint.

The instrument beingnow ready for i i operation, should be placed upon therail-` road track and the piston D broughtto bea-r against the periphery of one of the Wheels of the engine or car tobe moved. `The hand lever H `should thenl moved dOW`I`i-` i Ward, when by `means of `its actionathefl f plunger E is forced intotlie pump barrel C, and the piston Djis` consequentlydriven against the Wheel, Whichfis `urged forward:l and away from`theinstrument,` Y By raising@` the hand lever H, the lplungerflE isQwith` drawn for the next stroke, when in `conse-l y quence of the partial vacuum created by then" y 1 back stroke of the plunger E; the pressure of the atmosphere causes the piston I) to y descend to the bottom of the cylinderAQ. The instrument should` then be pushed f for- H Ward as much as" the engine lorl car hasllamil-"` j if vanced, and theprevlouslydescrlbed opel??` f ation should be renewed and carrledgon `as L often as occasion may `renden necessary.` i.

If, in consequence of leakagearound the"l plunger E, or piston D,` the supply offluidl Within the pump barrel Cshouldbe diminf i ished; provision` is `made for y replenishin the supply at the end lof the back strokelof` the plunger; as it is, completely Withdrawn from the pump barrel, thus affording"amplel means for entrance of the fluid from `thel reservoir I, into `the pump barrel C,1vvith `)i`itl y the intervention of `valves.;` 1 y y Having thus fully described the ,construcf tion and operation; of `my improvedghydraulic propeller, I donotclaim the multi-f,` x, plication of power by means of the hydrau` lic pump, such being; an old and `Wellknown y, i 1 l l; "``1oo`l and; desire to secure y by w device; but

What I do claim Letters Patent is;

The application of the `hydraulic i D to the purpose of propelling alocomotive 1 the peculiar arrangement of the plunger E engine or railroad car upon the track, by I pheric pressure, and Without the in'terven its direct action upon the periphery of the tion of Valves in the manner, and for the Wheel as herein described, combined with purpose substantially as herein set forth.
